Kink-like defects are subject of many investigations in several areas of physics. In particular, these structures can appear in cosmology [1]}, [2]}, optics communications [3]}, [4]}, superfluids [5]}, ferroelectrics [6]} and DNA [7]}. Lump-like defects are also of interest describing, for instance, bright solitons in optical fibers [8]}, [9]} and localized excitations in Bose-Einstein condensates [10]}.
In \((3,1)\)  dimensions, nontopological scalar field solutions were investigated in early universe cosmology [11]}, [12]}, [13]}, [14]}, and considered as a model for dark matter [15]}. In some of these applications, the lump can be stabilized if described by a complex scalar field, as done in q-ball models [16]}, or coupled with other charged matter fields [17]}. In this case the stable solution has a conserved Noether charge and is named by some authors as nontopological solitons.
